  • Rocket: Atlas V 551

  • Mission: AFSPC-11

  • Launch Date: Saturday, April 14, 2018

  • Launch Time: 7:13 p.m. EDT

  • Launch Broadcast: Live launch coverage will begin at 6:53 p.m. EDT

  • Launch Location: Space Launch Complex-41, Cape Canaveral Air Force Station

Mission Description: Air Force Space Command (AFSPC)-11 is a multi-manifested mission. The forward spacecraft is referred to as CBAS (Continuous Broadcast Augmenting SATCOM) and the aft spacecraft is EAGLE (ESPA Augmented GEO Laboratory Experiment).

Launch Notes: AFSPC-11 will mark the 77th launch of the Atlas V rocket since its inaugural launch in 2002 and the eighth in the 551 configuration, which produces more than 2.5 million pounds of thrust off the launch pad. This mission will be ULA’s 127th since the company was founded in December 2006.

Atlas V 551

Producing more than two and a half million pounds of thrust at liftoff, the Atlas V 551 rocket is the most powerful in the Atlas V fleet. In its more than 10 years of service, the 551 rocket has launched groundbreaking missions for our nation—from the critically important MUOS constellation to historic science missions including New Horizons, the first mission to Pluto and the Juno mission to Jupiter.

A United Launch Alliance (ULA) Atlas V 551 will launch two spacecraft to a geosynchronous transfer orbit.

The mission of CBAS is to augment existing military satellite communications capabilities and broadcast military data continuously through space-based, satellite communications relay links.

Primary mission objective for the EAGLE platform is to demonstrate a maneuverable ESPA based space vehicle design which can accommodate up to six hosted or deployable payloads in GEO, and can be cost effectively replicated for multiple payload missions to either a GEO, LEO or GTO orbit. EAGLE experiments will demonstrate enhanced capabilities in space system anomaly resolution and the capability to supplement ground based space situational awareness assets from a geosynchronous platform. EAGLE experiments will also provide new technologies to detect and identify system anomalies such as space weather events and characterize collision events due to micrometeorites.

Space Launch Complex-41

Space Launch Complex-41 (SLC-41) is ULA's East Coast launch pad for the Atlas V rocket. Launch vehicle integration and testing, spacecraft mate and integrated operations occur in the Vertical Integration Facility (VIF). The rocket rolls from the VIF to the launch pad prior to launch.
